coNNEeTnB-HEAD SUPPORT;

Application filed May 17, 1922. Seria11\`|'o. 561,70r8.

My invention relates to supports for the heads of automatic train connecters.

The purpose of my vinvention is to improve the connection.between the head and the bracket, simplifying it and at the same time securing a Imaximum, of flexibility to required' movement. v'

A'further purpose is to so connectv the head and yokejv with' the bracketthat the head Will swing 'abuta point nearly midway between the-'head andbra'clket and also about the 'bracket as a center'turn'ing equallyV in'all directions and attaining thebeneiits of these movements vindividually and a c omposite benefit' from'the automatic combination dof these movements.

' Further purposes Will appear in the specification and in the claims.

I have preferred to illustrate my invention by but one form, vselecting a form which is simple, practical, eiiicient, and inexpensive, Which employs a minimum number of parts and which at the same time Well illustrates the principles of my invention.

Figure lis a vertical longitudinal section through a train connecter head and supporting mechanism but with part of the bracket in elevation.

Figures 2 and 3 are sections of Figure 1 taken upon lines 2 2 and 3 3 respectively.

On account of the rough usage which .train connecters receive it is very desirable to have them inas simple a form and of as rugged construction as possible. The variation of position required of the head,

both vertically and horizontally, to correct for differ-ences in car-load1ng,ycurves, etc.7

' places a premium upon smoothness and ease of movement of the head with respectto the point of support, and has led to the production of the construction shown.

Describing the form shown in illustration but not in limitation The head is provided With the usual ears or horns 6, and is apertured at 7 8 and 9y to receive train pipe terminal tubes 10 upon which lmay be mounted fittings for connection With train pipes. The terminals are surrounded by springs 11. At the rear the openings are internally flanged, integrally or otherwise, to form the shoulders 12 against Which the springs 11 bear at the rear. At the front they bear against enlargements 13. Gaskets 14 are shown Within the tubes.

AThe terminal tubes are Vheld against eX- cessive projection by threaded collars 15 mounted upon threads `of approximately uniform diameter upon the tubes, on Which the collars' may therefore Vbe adjusted to adjust the tube projection and may be locled by lock nuts if desir-ed'.v -The .threads at the ends of the tubes are preferably tapered to make t-ight joints with the fittings. The structure as soy .far described, though my invention, is not intended to .be separately claimed inthis application.

About the center' ofthe head `I place a Y yoke-'like hollow rear yoke support-16preferably cast integral With thehead and spanning theA central tube but open at the' side at 17 to provide for attachment to this central tube of a Suitable fitting and proper connection to it through the lopenings in the yoke from a car train pipe. I have dotted such a fitting into Figure 1 though I have not included this in the section.

The yoke support 16 is notched at 18 to receive and position turned end 19 of the buffer spring 20. This spring surrounds a projection 21, upon the rear of the yoke support and bears against the iiange 22 vof the support.

The opposite end of the spring surrounds a flange 23 rigid with the bracket 24. The interior of this projection is flared forwardly at 25 and the bracket is apertured and is provided with a rearwardly facing spherical seat 26 about-the aperture. The spring at this end terminates in a. rearwardly turned end 27 which fits into a perforation 28 inthe bracket. l

An eye 29 upon the rear of the projection 21 affords a hold for a hook 30 upon a bolt 31 VWhich passes through the opening in the bracket and through Va spherical member 32 resting inthe spherical seat 26. This member maybe a nut or a Washer, and, even if itself a'nut, may be used With a nut 34. The bolt is tightened and held by means of one or more nuts, as indicated and places the spring 20 under the desired compression. At the same time the spring maintains the head normally in the position shown While it is free to move in all directions, swinging about the hook or about the spherical seat. In the latter case the `member 32 turns against the seat, and in either case there is a7 i eyebolt1 Within the spring. The parts areV Y then connected with the bracket so that the -vIn assemblage the spring is placed in po.- sition about the head projection and With the end 27 rits Within the opening in the bracket at 2S and the spring surrounds the part 23.

'y In the meantimethe bolt is passed through `The intermediate pivotal point, spacedV Well i'roin the head by the yoke support and the extension Within the spring back of the support, offers considerabie advantage in 1t- Seli` and also cooperates with the movement about thebraeket. Y Y It Willbe evident that my disclosure herein will suggest to others skilled-in theVV art various ways in which all or part of the benet of my invention may be secured Without copying the structure-illnstrated and it is -iny purpose to cover herein all such modifications and changes as come Within the spirit and scope of'rny invention.

Having ythus describediny invention what I claim as'nexv and desire to securevby Lettersy Patent is f l l. In a train pipe connecter, .a connecter head having a rearvvardlyfextending hollow support apertured at" the sidey'a' springrpressed pipe terminal Within the support adapted to connect With a train pipe through the sidev opening yand to move back and forward Within the body of the head and the supportl an eye at the rear-oi, the support, a spring surrounding the eye', a bracket withl which the rear of the' spring engages and a hook rod engageable with the bracket and eye and inaii'itaining the spring 1n coinpression. ;V y
